Procedurerepmi_c ( Replace marker with integer ) void repmi_c ( ConstSpiceChar * in, ConstSpiceChar * marker, SpiceInt value, SpiceInt outlen, SpiceChar * out ) AbstractReplace a marker with an integer. Required_ReadingNone. KeywordsCHARACTER CONVERSION STRING Brief_I/OVARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- in I Input string. marker I Marker to be replaced. value I Replacement value. outlen I Available space in output string. out O Output string. MAXLI P Maximum length of an integer. Detailed_Inputin is an arbitrary character string. marker is an arbitrary character string. The first occurrence of `marker' in the input string is to be replaced by `value'. Leading and trailing blanks in `marker' are NOT significant. In particular, no substitution is performed if `marker' is blank or empty. value is an arbitrary integer. outlen is the maximum allowed length of the output string `out'. This length must be large enough to hold the output string plus the null-terminator character. If the output string is expected to have N characters, `outlen' should be at least N+1. Detailed_Outputout is the string obtained by substituting the text representation of `value' for the first occurrence of `marker' in the input string. `out' and `in' must be identical or disjoint. ParametersMAXLI is the maximum expected length of the text representation of an integer. 11 characters are sufficient to hold any integer whose absolute value is less than 10 billion. This routine assumes that the input integer is such that its string representation contains no more than MAXLI characters. Exceptions1) If `out' does not have sufficient length to accommodate the result of the substitution, the result will be truncated on the right. 2) If `marker' is blank or empty, or if `marker' is not a substring of `in', this routine leaves the input string unchanged, except that trailing blanks will be trimmed. This case is not considered an error. 3) If any of the `in' or `marker' input string pointers is null, the error SPICE(NULLPOINTER) is signaled. 4) If the `out' output string pointer is null, the error SPICE(NULLPOINTER) is signaled. 5) If the `out' output string has length less than one character, the error SPICE(STRINGTOOSHORT) is signaled. FilesNone. ParticularsThis is one of a family of related routines for inserting values into strings. They are typically to construct messages that are partly fixed, and partly determined at run time. For example, a message like "Fifty-one pictures were found in directory [USER.DATA]." might be constructed from the fixed string "#1 pictures were found in directory #2." by the calls #include "SpiceUsr.h" . . . #define STRLEN 81 . . . repmct_c ( string, "#1", 51, 'c', STRLEN, string ); repmc_c ( string, "#2", "[USER.DATA]", STRLEN, string ); which substitute the cardinal text "Fifty-one" and the character string "[USER.DATA]" for the markers "#1" and "#2" respectively. The complete list of routines is shown below. repmc_c ( Replace marker with character string value ) repmd_c ( Replace marker with double precision value ) repmf_c ( Replace marker with formatted d.p. value ) repmi_c ( Replace marker with integer value ) repml_c ( Replace marker with logical value ) repmct_c ( Replace marker with cardinal text ) repmot_c ( Replace marker with ordinal text ) ExamplesThe numerical results shown for this example may differ across platforms. The results depend on the SPICE kernels used as input, the compiler and supporting libraries, and the machine specific arithmetic implementation. 1) The following example illustrate the use of repmi_c to replace a marker within a string with the text representation of an integer value. Example code begins here. /. Program repmi_ex1 ./ #include <stdio.h> #include <string.h> #include "SpiceUsr.h" int main( ) { /. Local parameters. ./ #define STRLEN 81 /. Local variables. ./ SpiceChar instr [STRLEN]; SpiceChar marker [STRLEN]; SpiceChar outstr [STRLEN]; /. 1. Single marker ./ strncpy( marker, "#", 2 ); strncpy( instr, "Invalid value. The value was: #", 33 ); repmi_c ( instr, marker, 75, STRLEN, outstr ); printf( "Case 1: Single marker.\n" ); printf( " Input : %s\n", instr ); printf( " Output: %s\n", outstr ); printf( "\n" ); /. 2. Multiple markers ./ strncpy( marker, " XX ", 5 ); strncpy( instr, "Left > Right endpoint. Left: XX; Right: XX", 43 ); repmi_c ( instr, marker, 2035, STRLEN, outstr ); printf( "Case 2: Multiple markers.\n" ); printf( " Input : %s\n", instr ); printf( " Output: %s\n", outstr ); printf( "\n" ); return ( 0 ); } When this program was executed on a Mac/Intel/cc/64-bit platform, the output was: Case 1: Single marker. Input : Invalid value. The value was: # Output: Invalid value. The value was: 75 Case 2: Multiple markers. Input : Left > Right endpoint. Left: XX; Right: XX Output: Left > Right endpoint. Left: 2035; Right: XX RestrictionsNone. Literature_ReferencesNone. Author_and_InstitutionN.J. Bachman (JPL) J. Diaz del Rio (ODC Space) I.M.
